Question

A recipe calls for 32 fluid ounces of heavy cream. How many 1-pint containers of heavy cream are needed to make the recipe?

Answer 1

Need 2 of containers of size 1 pint

Explanation:

Assumption: Using US liquid measure

Thus we have 1 fluid oz =0.0625 pints

So by using ratio

`" "("Pints")/("Fluid oz") = (0.0625)/(1)`

But we need 32 fluid oz's so multiply by 1 but in the form of `32/32`

Note that `(32/32 = 1)` and anything multiplied by 1 does not change its value.

`" "32/32xx0.0625/1 = ("2 pints")/("32 fluid oz's")`

So for the target of 32 fluid oz we need two containers of 1 pint each.
